In reply to MrRiley:
I climbed water ice for 5 days last week with new Quarks. Petzl hammers on both of them, standard Ice picks (T-rated) and no weights. They felt great and it wasn't hard to get good placements even on reasonably hard ice.
I tried my guide's (old) Nomics with pick weights for a pitch and actually preferred my Quarks, but I may just have not had enough time to get used to them. The balance was way different (obviously). I'm tempted to try weights on the Quarks, though, and see what happens. Expensive mistake if I hate it though!
